Ideal for athletes, the SM-110 finger pulse oximeter measures oxygen levels and pulse rates before and after hikes, pickup games, and sprints through a lionís den. Stats appear on a clear readout that consumes so little power that a pair of AAA batteries will keep it glowing for up to 30 hours. Clocking in at only 50 grams, the lightweight device stays within an armís reach thanks to its included carrying case and elastic cord.
